Question

what determines the path that an object in projectile motion follows? (ignore air resistance)
gravity only
inertia only
gravity and inertia
neither gravity or inertia

Explanation:

In projectile - motion without air resistance, inertia causes the object to move horizontally at a constant velocity (Newton's first law). Gravity acts vertically, causing the object to accelerate downwards. The combination of these two factors determines the parabolic path of the object.

Answer:

C. gravity and inertia
